The invention relates to printingpresses andmore particularly to the mechanism employed in rotary newspaper presses for" displacing or equivalently indicating certain papers in the delivered stack, therebyto divide the stack or row of delivered papers into groups each of which contains a desired orpredetermined number of papers.

Objects and advantages of the invention will be set forth in part hereinafter'and in part will be obviousherefrom, or may be learned by practice with the invention, the

same being realized and attained by means of the instrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel parts,

constructions, arrangements, combinations and improvements herein shown and described.

The accompanying drawings, referred to herein and constituting a part hereof, i-llustrate one embodiment of the invention, and together with the description, serve to explain the principles of the invention.

Of the drawings Fig. 1 is a side elevation, with parts in section and with parts broken away, of a mechanism embodying the invention;

Fig. 2 is an end elevation, with parts in I; section, looking at'Fig. 1 from the right Fig. '3 is a longitudinal, vertical section, taken substantially on line 33 of Fig. 2;

Fig. i is a detached, fragmentary detail in horizontal section taken substantially on line 4l4t of Fig. 2; and 1 Fig. 5 is a side elevation of the delivery mechanism of a rotary newspaper press with certain of the mechanism of the invention applied thereto, and showing certain mechanism which is also shown at the lower rightv hand-partof Fig. 2.

In the delivery mechanism of rotary newspaper presses it is customary to have the mechanism designate or mark groups consisting of a predetermined number of newspapers in the delivered stack or row, the designation being usually by displacing the last paper of the desired number in the continuous row or stack upon the delivery belt.

The present invention is directed to providingmeans for nicely adjusting the flipper, forming apart of the designating or markingmechanism, whether or not the number ofnewspapers in the groups are varied or changed.

The present invention is also directed to providing meansfor varying the operation or periodicity of the designating or marking mechanism so as to indicate or. mark groups of different numbers of newspapers asmay. bedesired, andto provide for consequent and concomitant changes or variations in the operation. of thegvarious cooperating mechanism.

The usual construction for such a mechanism comprises in conjunction with the rotary. flyof .the folder, which lays the completed or folded newspapers in an even row orstack on the delivery belt, a flipper or swinging finger, operating in a definite time relation with the fly, and which periodically lifts or displaces a paper as it is delivered fromtheflyonto the belt so'that it will project above the other papers in the row or stack on the delivery belt and so designate or mark a group containing a predetermined number of newspapers, the number being dependent on the time relation of the flipper finger to the rotary delivering fly.

The present invention is directed to nicely adjusting the flipper, whether or notthe number of newspapers in the designated groupis varied. The invention is also direoted to changing the relation between flipper finger and the rotary fly so that the number ofwpapers in the designated group may, if desired, be varied, and especially to thus vary the designated number in a relatively small degree, as say from twenty-five to twenty-six papers. The reference to a ro-' tary fly and other details of the usual form of delivery must not be construed as limiting the invention, as it could be applied to other forms of delivery mechanism.

In connection with the foregoing, rectifying means are provided for maintaining to a 'nicety, or recovering, the proper relation between the folder fly and the actuating cam, or equivalent actuating mechanism for the flipper finger. This nicety of adjustment is obtained whether or not the designating or marking mechanism is varied to change the count of the newspapers. when the gear drive is changed to effect the change in the number of papers in the group, the rectifying means wil also insure proper relation between the folder fly and the actuating cam fQnthe flip er finger as to secure the proper count or esignation in conjunction with making the desired changes in counting mechanism.

Other features and objects of the invention will be first set forth in connection with the appended detailed description of the present preferred embodiment and it .will be understood that the foregoing. general .de scription and the following detailed descriptionof the invention are illustrative and exem lary but are not restrictive of the invan ion. V

Referring now to the embodiment of the invention, illustrated by way or example in the accompanying drawings and. referring primarily tocertain otthe folding anddeivery devices of a rotary printing press (Fig. the rollers l and 2 of the transverse folder, which makes the final cross-fold in the newspa er, are journaled in the frame 3. A'

rotary 4 has its shaft 5 journaled in the frame 3, and is provided with a plurality of arms 6, between which are the spaces 7 into which the completed newspaper s'are dropped or deliveredfrom the folding rollers 1 and 2. .-The rotary fly 4 lays the completed papers upon 1a suitable delivery device, such as a traveling belt 8, running over a roller-:9, and having supporting and tensioning rollers 10 and 11 carried, respectively, by arms-l2 and 16, fixed to a shaft- '14, journaled in the machine frame. 1 The finished papers are laid upon the belt 8 inau row or series uniformly. spacedor disposed, and for theapu'rpose of indicating, designating or marking groups containing a given number of papers, it iscustomary to periodically displace apaper in the series or rows upon the belt 8, the device effecting this operation after the delivery of the predetermined number of papers. Thus, each projectingpaper will mark a group with agiven number of papers therein between it and the next projecting paper. Thus the papers may be picked up and handled in exact numbers without counting.

of which is joui-nalcd a cam roller 19, co-

operating with a cam 20.

The mechanism so far as described is of a usual or standard form, and it will be understood that the present invention may be applied to other forms of newspaper delivery devices than that herein exen'iplarily shown.

It is desirable to get a nicety of adjustment of the flipper without changing the count of the newspapers in any group.

ltcis also desirable frequently to change the number of papers in each marked or indicated group of thedelivered papers, that is, to have the mechanism displace a newspaperafter a given number have passed, or optionally or selectively, after a different given number of newspapers have passed.

,It is further frequently desirable to vary the operation of the indicating means to change the number in the group relatively very little, for instance, to have the mechanism constructed and operated so as to mark or indicate either agroup of twenty-five newspapers or twenty-six newspapers, al-

though it will be understood that these numbers are merely illustrative.

Accordingly, meansare provided for varying the period of operation of the flipper arm 15, said means being )referably arranged and located between the therefor. For convenience, the. detailed description of the present preferred embodiment will begin with the general driving mechanism and will end up at the flipper arm.

. A driving gear 34 fixed upon a shaft 35, journaled in the general frame 3. In the preferred embodiment a change gear, or speed change gear mechanism cooperates with the driving gear wheel 34, to change the period of operation of the flipper arm 15. j A pinion 36 is shown in mesh with gear wheel 34, this gear wheel being fixed on a shaft 37 which is journaled in the end of the arm 38 of a bell crank lever 39, which bell crank lever is loosely pivoted by shaft 40, later to be described, Fixed also to shaft 37 to rotate with the pinion 36 is a pinion 41 which pinion is in mesh with a gear wheel 42 fixed on the shaft 40. I

The alternative drive of the change gear, or speed changing gear, comprises a pinion 43, fixed to a shaft 44, and a pinion 45 is also fixed to shaft 44.. This shaft is journaled in an arm 46, extending outwardly from the arm 470i the bell cranklever, 39. .Pinion 45 Is also inmesh with the gear wheel 42. bell crank is provided vxith a handle 50, and with a bolt and slot holding device 51. Thus when the IIIQChtIlllF-illl is in the position of Fig. 1, thedrive from gear wheel 34 is through pinions 36 and ill. to the gear wheel 42.. ,Whcn the bell crank lever is rocked bv moving handle tothe left,pinion 36 is thrown out of mesh with go: r wheel 34-, and pinion 43 pper arm and the drive is thrown'finto mesh with the gear wheel 34'. The ratios of the respective pinions aresuch that, they will drive the gear wheel 42 at different speeds, so, as to effect the desired differencein the period of operation of the flipper arm 15, and of its actuating cam to eflect the desired difference in counting the papers.

As embodied, the further driving connections to the flipper arm actuating cam 20 comprise means for rectifying or neutralizing the change caused in the relative position ofthe cam 20 and the folder fly 4, by shifting the change gear mechanism. This mechanism operates as stated to rectify the change in position between the cam' and fly and thereby to get theproper count in the delivered newspapers.

In the embodied form, this rectifying means is applied to the driving connections to the cam 20 about to be described. Fixed on shaft 40 is a worm 58 (Figs. 2, 3 and 4) connected to the shaft by a spline 59, the worm accordingly rotating with the shaft but being slidable thereon. Means are provided for controlling the position of the worm along its shaft, the required movement being relatively very slight, to compensate for an opposite movement, caused by the operation of the change gear mechanism already described.

As embodied, a non-rotating washer 60 encircles the shaft, and abuts on the worm,

the outer face 61 thereof being beveled. Abutting on the wedge-like washer 60 is a sliding, bifurcated Wedge 62 beveled complementarily with washer 60. The shaft 40 passes through a central recess in the wedge, and the arms 63 and 64 of the wedge extend horizontally above and below the shaft. On

its opposite face the wedge 62 bears against the frame 3.

Means are provided for movmg the wedge 62 to and fro accurately and minutely with respect to the shaft 40, and as embodied, a screw shaft 68 is journaled in a bracket 69, carried upon the frame. The shaft has a hand wheel 70 at the exterior end thereof, with its hub abutting on the bracket 69, and with a positioning collar 71 fixed thereto on the other sideof the hub, whereby the rod is rotatable in the journal bracket 69 but is held against longitudinal movement. At its other end rod 68 is provided with a screw thread 7 2, which is threaded into the tapped projection 7 3 of the wedge 62. I

' Thus as the hand wheel 70 is rotated, the wedge 62 is moved finely and accurately to and fro to correspondingly move the worm 13 58 along the shaft 40, thereby eflecting a slight compensating or correctional relation between, the worm and its Worm wheel '80, later to I be described. A helical spring 7 5 is in compression between the hub of the worm 58 and a collar 76, fixed on the shaft bracket 83 supportedby the machine frame,

the hub of the Worm wheel abutting againstone end of the bearing 82. Abeveled gear wheel 85 isfixed to the other end of shaft 81, and has its hub abutting on the A opposite end of the bearing 82.

Meshing with the beveled gear 85 is a beveled gear 86 rotatably mounted on a shaft 87 journaled in a supporting bearing and standard 88, fixed to the machine frame.

Fixed to bevel gear 86 to rotate therewith is a gear wheel 92, which meshes with a gevar wheel 93, rotatably carried on a shaft 94. Gear wheel'93 has its hub '95 integral with or fixed to thehub 96.of a part or member of the flipper arm actuating cam 20.

Thus when the hand wheel 70 is turned to move the adjusting or position-varying or controlling wedge 62, the worm. 58 is moved longitudinally along its shaft 40, and by means of its movement it is; possible to adjust the cam disc 20 to exact position.

Means are likewise provided for correspondingly setting the flipper finger or kick er and this is a very precise and delicate operation. In the embodied form of means for erecting this, the hub 96 of the cam 20 is keyed to the shaft 94, the hub carrying a circular flange 100. The cam 20 proper is circularly centrally recessed so that it will rest and also rotate upon the periphery of the circular flange 100. The flange 100 and the cam 20 are connected together to be angularly or circularly relatively positionable by suitable means, such as bolt and slot connections 102 passing through a slot in one and screwed in to the other, and which may be of usual form.

In the embodied form of means for angularly positioning the rim 20 on the central part 100, as above referred to, there is rotatably mounted in the cam 20a short shaft 106, to which is fixed a hand-wheel 107, on one face of the cam. Fixed also on shaft 106, and nested on the oppositeface of the cam in alinement with the flange 100 is a pinion 108.

Afew gear teeth 109 are formed in the pe- V ripheral edge ofthe circular flange 100. By rotating the hand wheel 107, which is friction-tight, a very nice and'precise positioning of the cam 20 with respect to its supporting hub 94 and the train of driving mechanism is secured. V

The cam 20 is provided with one or more depressions 110, with which the cam roller 19 coacts to actuate the kicker arm or flipper 15. If desired, a silencing plate 112 may be provided for the depression 111, and thereby the number of designated papers may be doubled. The plate 112 is pivotally supported at 113 and [has anarcuate bolt and slot connection is journaledin a bearing 82, carried on a F 114, Mthth cam 20 whereby it may beheld E10 either the operative or inoperative posi Tt will be clear from the foregoing that the ieifltaht displacement of the flipper, due to cliahging the count of thenewspapers in any greener be corrected or compensated by idin the Worm ar 58 along its shaft by iidtha 'ng the We ge 62 through the hand WlieblTO'arid coo crating screw-threads. Or, the same correction or compensation can he seemed by adjusting the cam 20 upon the ineinbr 100. 'In the latter case, the worm adjustment would not be necessary.

"It'ivill be further noted that the adjustihht of the worm gear 58 can be made while the "ess is running. This is also true in tho cases Where it is desired to make the atliiistnl'ent simply by means of the adjustah e chm, fdr the cam moves so slowly that the parts can be readily adjusted while the pg'ess is in motion. It will also be noted from e foregoing description that the flipper adjustihentcan he made by the adjustable cam simply to insifre a nicety of adjustment of the flipper, 'ivithout any dependence whatever on or connection with the counting mechanism condoms" the number of newspapers in the groups. 6r, the sliding worm gear 58 controlled by the wedge 62 could be used for the samepm-pose, even if gears are not used to chan e'the cou'nt.

W en the gears are used to change the count, the 'Yositio'n of the flipper is adjusted J or rectified y eitherthc sliding'worm 58'and its operating connections, or by the adjust- !ible cam'20. Either mechanism is sutiicient to make the adjustment. Such an adjustment or rectification is necessitated by the fact that when the gears 36, 43 are shifted to change the count, shaft 40 is angularly shifted,which angular shi'ft would be transmitted through gears '80, 85, 86, etc. to cam 20 and would introduce an error in the count,unless compensi'ated for by either of the two described rectifying or adjusting devices.
